Synchronous lifting overcomes the single jack lifting weight should be inclined, resulting in damage to the weight and produce danger.
Synchronous lifting uses multi-top synchronous shunt valves, and the load of each top is balanced to keep the speed of lifting and dropping synchronously. It should also be considered that the ground may sag due to the uneven weight of the lifting object, which may cause artificial damage.
Synchronous lifting is equipped with pressure retention and overflow device to prevent overload, and equipped with safety valve to protect Synchronous lifting to achieve safe operation and the purpose of protection of lifting objects, pressure retention device is more suitable for the bridge construction with high pressure requirements of falling beam
1, if you need several jacks lifting at the same time, in addition to the correct placement of the jack, should use multiple shunt valve, and each
The load of the jack should be balanced, and attention should be paid to keeping the lifting speed synchronized. The possibility of subsidence due to uneven weight must also be considered
The situation is to prevent the danger of tilting the object being lifted.
2. When Synchronous lifting is used, the quick joint of the manual pump is first connected to the top, and then the position is selected and the oil release screw on the oil pump is tightened to work. To lower the piston rod, manually
The handwheel of the oil pump is slightly loosened in the counterclockwise direction, the cylinder is unloaded, and the piston rod is gradually lowered. Otherwise too fast a descent will be dangerous.
3, the jack is spring return structure, after lifting, you can quickly take out, but can not use the connected hose to pull the jack.
4, because the jack lifting stroke is small, the user must not exceed the rated stroke when using, so as not to damage the jack.
5, the jack should avoid severe vibration during the use of Synchronous lifting.
6, Synchronous lifting is not suitable for acid and alkali, corrosion
Users should check and maintain them regularly according to their use conditions
